The Advanced Settings button opens a further window with additional settings for the distributed clocks function. |
EtherCAT slaves feature integrated local clocks, which are synchronized by the EtherCAT master via special datagrams. For sample, the local clock of an EtherCAT slave can be used as reference clock, based on which all other clocks are synchronized.
By default, TwinCAT sets the first EtherCAT slave that supports the distributed clocks function as reference clock. This setting can be changed, although we recommend retaining the default setting.
